[eclipse.org-committers] Outage notice - Sunday, July 17 2005 6:00am Eastern
|
Greetings,
There will be an outage this coming Sunday from 6:00am to 8:00am Eastern
while we migrate the eclipse.org backend server to its permanent server.
A message will be posted to eclipse-dev and to the website shortly.
Critical services affected are CVS and Bugzilla, which will be
unavailable for most of the outage. Other services, such as the website,
RSYNC and mail, should not be affected by the outage. We simply want to
disable "writing" to files on our servers while we transfer the data to
the new servers. The search engine may be down a bit longer while I
force a complete reindex, but this is nothing critical.
CHANGES TO THE INFRASTRUCTURE - see below for more details.
- Load-balanced CVS - including EXTSSH
- Mirrored backend
- More Disk Space
- Faster backend
This migration will conclude hardware migrations at eclipse.org. If you
have any questions about the migration or how these changes affect you,
please do not hesitate to contact us directly. Thanks for your
understanding and cooperation.
Denis
- Load-balanced CVS - including EXTSSH
The current scenario where extssh and pserver CVS are not in sync will
disappear. Running builds using PSERVER will yield the exact same result
as running a build using EXTSSH. This was our initial intention when the
migrating occurred in March, but we ran into permissions problems that
forced us to isolate CVS to one server.
Although we'll do our best to prevent this, some committers may lose
commit rights to some modules - please advise us ASAP and we will fix
the problem immediately.
Also, the cvsstat http links will disappear sometime next week:
http://dev.eclipse.org/cvsstat/eclipse
http://dev.eclipse.org/cvsstat/tools
etc...
- Mirrored backend
The backend server is mirrored to another server, with automatic
failover. Should the backend server die, the secondary will pick up
duties automatically within 1 minute. The added bonus is that the
secondary server will be used for read-only access to databases (such as
Live Stats for Downloads)
- More Disk Space
The new backend server has 1TB of disk space. We will be maintaining
tight download disk quotas because our mirror sites do not have this luxury
- Faster backend
The new backend servers have four processors, 16 GB of RAM and 15 disks
spread across two controllers. The current backend server (which in
fact is a front-end node we've been using in the interim) has a major
disk bottleneck in that it only has three disks on one controller. The
current backend server will then be used as "node4" in our front-end
cluster.
